Electrode Boiler with Thermal Energy Storage
Shuangliang’s electrode boiler combined with thermal energy storage technology is especially suitable for applications with fixed cycles or intermittent demands for steam or thermal energy.

The system adopts the following technical approach:

The electrode boiler generates steam using electricity, which can come from solar panels (green power) or the power grid.
The thermal energy storage system stores heat in the form of high-pressure hot water inside an insulated tank. This stored energy can be released when steam or heat is needed.

Key Advantages:


Utilizes low-cost electricity (e.g., off-peak night-time electricity or surplus renewable energy) for heat generation.
Stores energy during low-demand periods and releases steam or thermal energy during peak demand, maximizing energy efficiency and cost savings.
